GP 6 How to Check a Motor for Xerox VersaLink C7020 C7025 C7030 C7000 Printer?
Posted by Xwk Tech on
This procedure describes how to check the motors that follow:
• Two Wire DC Motors.
• Four Wire Stepper Motor.
• Six Wire Stepper Motor.
Initial Actions
WARNING: Ensure that the electricity to the machine is switched off while performing tasks that do not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause death or injury. Moving parts can cause injury.
1. Check that the motor is free to rotate.
2. Check that all the motor’s mechanisms are clean, free to move and lubricated correctly.
3. Enter the component control code for the motor. Refer to dC330. Run the motor for 30 seconds. If the motor shows signs of, or can be heard to slow down, then the motor is defective. Replace the motor.
4. Perform the appropriate procedure:
• Two Wire DC Motors.
• Four Wire Stepper Motor.
• Six Wire Stepper Motor.
NOTE: The voltages, PJ numbers, pin numbers and PWB names shown are an example only.
Two Wire DC Motors
NOTE: In cases where the motor may be driven forward or backward, the same 2 feed wires are used, but the voltages on them are reversed, to reverse the motor direction. Such motors may have 2 component control codes, for forward and reverse. A typical application is a tray lift motor with a tray-up and a tray-down direction.
• Disconnect PJB (Flag 2). Check that +24V is measured when the component control code for the motor is entered.
• Disconnect PJA (Flag 1). Check for +24V on the LVPS.
• Disconnect PJC (Flag 3). Check that the signal changes on the ESS PWB when the component control code for the motor is entered.
• Check the wiring and the connectors for the motor circuit.
Four Wire Stepper Motor
NOTE: A stepper motor with an internal open circuit may appear to be fully functional under dC330 component control. However, under normal operation it will run with intermittent failure.
Use the standard digital meter to check that the resistance of the stepper motor coils are similar.
• Disconnect PJH (Flag 6). Check the motor on pulses on the harness when the component control code for the motor is entered.
• Disconnect PJJ (Flag 6). Check the motor on pulses on the harness when the component control code for the motor is entered.
• Check the wiring and the connectors for the motor circuit.
Six Wire Stepper Motor
NOTE: A stepper motor with an internal open circuit may appear to be fully functional under dC330 component control. However, under normal operation it will run with intermittent failure.
Use the standard digital meter to check that the resistance of the stepper motor coils are similar.
• Disconnect PJF (Flag 5). Check the +24V supply and the motor on pulses when the component control code for the motor is entered.
• Disconnect PJD (Flag 4). Check the +24V, +5V and 0V supplies.
• Check the clock pulses (Flag 4).
• Check that the signal on PJD pin 13 (Flag 4) changes when the component control code for the motor is entered.
• Check the wiring and the connectors for the motor circuit.
